Hin Luk Bat

This dive is accessible via boat within 30 minutes from Koh Chang’s Bangbao Pier. The convenience of the location is part of the reason why it is a popular dive site. In this site, you can find pinnacles that drop down to 20 meters below the sea surface. You can spend an hour for each dive to explore pinnacles at varying depths. Some of the notable fish species you will encounter include barracudas, angel fishes, and butterfly fishes.

Koh Wai

Do you fancy spotting reef sharks during your dive? You must head to Koh Wai during your dive explorations in Koh Chang. You can find most of them resting on the seabed at this site. It is also a pretty calm dive site that is suited for beginners and snorkelers.

Hin Rap

This dive site is about 2 kilometers from Hin Luk Bat but is sought after by dive enthusiasts for its rock pinnacles and Staghorn corals. There is also a rich diversity of small reef fishes that is considered the main attraction in this dive site.

Koh Kra

This gently sloping reef is filled with gardens of staghorn coral and lively reef fish. You can even find the corals at 5 meters from the water surface. If shallow dive is what you prefer, this dive site is definitely a great choice for that.

Koh Rang

If you want to experience a diversity of diving and snorkeling on your trip, Koh Rang is a must-add to your dive trip. You can find small islands and rock pinnacles at this dive site. The average depth of each dive is anywhere from 10 to 15 meters; hence, it is mostly a shallow dive. It is therefore a notable choice for beginners.

Wreck of the Thonburi

In 1941, the Thonburi sunk to the ocean floor at the southeastern tip of Koh Chang. Today, this sunken ship is a famous destination for dive enthusiasts who travel to Koh Chang. The shipwreck has transformed into an artificial reef. The only downside is that visibility is extremely challenging at this site because of the amount of silt. For this reason, most dive tour companies do not run trips on the area.

Wreck of the Chang

The HTMS Chang was sunk by the Thai Navy in 2012. Since then, this shipwreck has created an artificial reef underwater. The shipwreck offers a dive depth of 30 meters but you can reach the captain’s cabin within 12 meters of your dive. The shipwreck is one of the largest in Thailand at 100 meters long. There is also rich diversity in marine life that includes groupers, squids, octopuses, and barracudas, to name a few.

There are two islands in Thailand named Koh Chang – but for this guide, it refers to the larger one located along the northeastern coast of Thailand (located close to Cambodia). The name Koh Chang literally translates to Elephant Island.

Therefore, it is not uncommon to find elephants here although they are not native to the island. The name can also be attributed to the shape of the headland.

The island of Koh Chang is part of an archipelago consisting of 51 islands. The land area of the island measures at 30 kilometers long and 14 kilometers wide. Even though it is not as vibrant as other islands in Thailand as far as tourism are concerned, that is not to say that it is underdeveloped.

It is one of the hidden gems of Thailand that those who were daring enough to visit are rewarded for.

The island is divided into 14 major areas that you can choose from as base during your trip. Each location will have something unique to offer, whether you are seeking an idyllic or adventurous holiday.
